TECHNICAL FIELD

This application relates to the field of communications technologies,and in particular, to a scheduling request configuration method andsending method, and a corresponding apparatus.

BACKGROUND

In a 5th generation (5G) mobile communications system, a user equipment(UE) may have a plurality of services at the same time. Services havinga same quality of service (QoS) requirement may be mapped to a samelogical channel for transmission. Services having different QoSrequirements may be mapped to different logical channels fortransmission. During transmission, the services having the same QoSrequirement need to be transmitted by using an uplink grant (UL grant)of a physical transmission parameter set (which may include a subcarrierspacing, a cyclic prefix length, a transmission time length, and thelike) that can support the QoS requirement.

However, in the prior art, when allocating an uplink grant to the UE, anetwork device does not distinguish between transmission requirements oflogical channels of the UE, and there is a lack of a mechanism forallocating, to a logical channel of the UE, an uplink grant matching aQoS requirement of the logical channel.

SUMMARY

This application provides a scheduling request configuration method andsending method, and a corresponding apparatus, to resolve a prior-artproblem that there is a lack of a mechanism for allocating, to a logicalchannel of UE, an uplink grant matching a QoS requirement of the logicalchannel.

According to a first aspect, this application provides a schedulingrequest SR configuration method, including: receiving, by user equipmentUE, control signaling sent by a network device, where the controlsignaling is used to configure, for the UE, an SR configurationassociated with at least one logical channel and at least two SRresource configurations associated with the SR configuration, the atleast one logical channel may be a plurality of logical channels havinga same quality of service requirement, and the SR resourceconfigurations indicate physical resources used to transmit an SRassociated with the at least one logical channel. When the UE needs tosend an SR associated with one of the at least one logical channel, theUE may transmit the SR based on a physical resource indicated by one ofthe at least two SR resource configurations.

In the foregoing technical solution, the UE may send, by using thephysical resource indicated by the one of the at least two SR resourceconfigurations associated with the logical channel of the UE, the SRassociated with the logical channel. After receiving the SR sent byusing the physical resource, the network device may determine a physicaltransmission parameter set mapped to a location of the physicalresource. The physical transmission parameter set mapped to the locationof the physical resource may include at least one of a subcarrierspacing, a cyclic prefix length, physical uplink shared channel (PUSCH)transmission duration, a time interval between control signaling forscheduling PUSCH transmission and time PUSCH transmission, and anavailable serving cell. Then, the UE allocates, to the UE, an uplinkresource meeting the physical transmission parameter set, to meet thequality of service requirement of the logical channel. In addition, theat least one logical channel of the UE may be associated with the atleast two SR resource configurations, so that when a physical resourceindicated by one of the SR resource configurations is unavailable, theUE can transmit an SR by using a physical resource indicated by anotherassociated SR resource configuration. Therefore, the UE can transmit theSR in a timelier manner, thereby reducing an SR transmission latency.

In some embodiments of the first aspect, the SR configuration includesSR-prohibit timer duration, the UE sets an SR-prohibit timer for the SRconfiguration, and starts the SR-prohibit timer after transmitting an SRon a physical resource indicated by any one of the at least two SRresource configurations, the SR-prohibit timer is configured toprohibit, during a running period of the SR-prohibit timer, the UE fromtransmitting an SR on a physical resource indicated by any one of the atleast two SR resource configurations, and duration for which theSR-prohibit timer runs after being started each time is the SR-prohibittimer duration. In the foregoing technical solution, the UE sets theSR-prohibit timer for the SR configuration. This can avoid atransmission resource waste caused when an SR associated with a logicalchannel is resent only because the UE receives no uplink resource grantdue to a normal transmission latency after the network device hasnormally responded to a previously sent SR, and can also prevent thenetwork device from receiving a repeated SR.

In some embodiments of the first aspect, if an SR associated with afirst logical channel in the at least one logical channel is triggeredand not canceled, the UE determines the SR configuration associated withthe first logical channel and a first SR resource configurationassociated with the SR configuration on an activated first BWP; and foreach time unit, if the user equipment has a physical resource indicatedby the first SR resource configuration in the current time unit and theSR-prohibit timer that is set for the SR configuration does not run, theUE transmits, on the physical resource indicated by the first SRresource configuration, the SR associated with the first logicalchannel. In the foregoing technical solution, when at least two SRresource configurations associated with the first logical channel areconfigured on different BWPs, the UE sends the SR by using the physicalresource indicated by the first SR resource configuration configured onthe activated first BWP, to ensure that the UE can transmit the SR in atimely manner.

In some embodiments of the first aspect, after the UE transmits, on thephysical resource indicated by the first SR resource configuration, theSR associated with the first logical channel, if a BWP activated by theuser equipment changes from the first BWP to a second BWP and the SRassociated with the first logical channel is not canceled, the userequipment determines a second SR resource configuration associated withthe SR configuration on the activated second BWP; and for each timeunit, if the user equipment has a physical resource indicated by thesecond SR resource configuration in the current time unit and theSR-prohibit timer that is set for the SR configuration does not run, theUE transmits, on the physical resource indicated by the second SRresource configuration, the SR associated with the first logicalchannel. In the foregoing technical solution, when the BWP activated bythe UE changes and the SR associated with the first logical channel isnot canceled, the UE may continue to send, on the activated second BWPafter the change, the SR by using the physical resource indicated by theSR resource configuration associated with the first logical channel, sothat the network device can allocate an uplink transmission resource tothe first logical channel in a timely manner.

In some embodiments of the first aspect, if an SR associated with afirst logical channel in the at least one logical channel is triggeredand not canceled, the UE determines an SR configuration associated withthe first logical channel, a third SR resource configuration associatedwith the SR configuration on an activated third BWP, and a fourth SRresource configuration associated with the SR configuration on anactivated fourth BWP; and for each time unit, if the SR-prohibit timerthat is set for the SR configuration does not run and the user equipmenthas a physical resource indicated by the third SR resource configurationor the fourth SR resource configuration in the current time unit, the UEtransmits, on the physical resource, the SR associated with the firstlogical channel. In the foregoing technical solution, when theSR-prohibit timer does not run, the UE may transmit the SR by using acurrently obtained physical resource for transmitting the SR associatedwith the first logical channel, and is not limited to transmitting theSR resource on a physical resource indicated by an SR resourceconfiguration on a specific BWP. Therefore, utilization of a physicalresource for transmitting the SR can be improved, and the SR can betransmitted in a timely manner, so that a time consumed by the UE towait for an uplink resource grant is reduced.

In some embodiments of the first aspect, if an SR associated with afirst logical channel in the at least one logical channel is triggeredand not canceled, and none of BWPs on which at least two SR resourceconfigurations associated with the first logical channel are configuredis activated, the UE activates a first BWP on which a first SR resourceconfiguration in the at least two SR resource configurations isconfigured; and for each time unit, if the user equipment has a physicalresource indicated by the first SR resource configuration in the currenttime unit and the SR-prohibit timer that is set for the SR configurationdoes not run, the UE transmits, on the physical resource indicated bythe first SR resource configuration, the SR associated with the firstlogical channel. In the foregoing technical solution, the UE mayactively activate a BWP, namely, the first BWP, in a plurality of BWPswhen the plurality of BWPs on which a physical resource for transmittingthe SR associated with the first logical channel is configured are notactivated, and the SR associated with the first logical channel needs tobe sent, and send the SR by using the physical resource indicated by theSR resource configuration that is on the first BWP and that isassociated with the first logical channel. Therefore, the SR istransmitted in a timely manner, so that a time consumed by the UE towait for an uplink resource grant is reduced.

In some embodiments of the first aspect, before the UE activates thefirst BWP, the UE determines that an SR transmission occasion indicatedby the first SR resource configuration is earlier than an SRtransmission occasion indicated by any SR resource configuration otherthan the first SR resource configuration in the at least two SR resourceconfigurations. In the foregoing technical solution, when none of theBWPs on which the at least two SR resource configurations associatedwith the first logical channel are configured is activated, the UEactivates the first BWP on which the physical resource that can beearliest used to transmit the SR associated with the first logicalchannel is configured, to transmit the SR in a timely manner, therebyreducing a time consumed by the UE to wait for an uplink resource grant.

According to a second aspect, an embodiment of the present disclosureprovides an SR transmission method, including: receiving, by UE, controlsignaling sent by a network device, where the control signaling is usedto configure, for the UE, an SR configuration associated with the atleast one logical channel and an SR resource configuration associatedwith the SR configuration; activating, by the UE, a first BWP if the UEhas an SR that is associated with a first logical channel in the atleast one logical channel and that is triggered and not canceled, the SRresource configuration is configured on the first BWP, and the first BWPis not activated; and transmitting, by the UE on a physical resourceindicated by the SR resource configuration, the SR associated with thefirst logical channel. In the foregoing technical solution, the UE mayactively activate the first BWP when the first BWP on which the physicalresource for transmitting the SR associated with the first logicalchannel is configured is not activated, and the SR associated with thefirst logical channel needs to be sent, and send the SR by using thephysical resource indicated by the SR resource configuration that is onthe first BWP and that is associated with the first logical channel.Therefore, the SR is transmitted in a timely manner, so that a timeconsumed by the UE to wait for an uplink resource grant is reduced.

In some embodiments of the second aspect, all SR resource configurationsof the UE are configured on the first BWP, so that the UE quicklylocates a physical resource for transmitting an SR.

In some embodiments of the second aspect, SR resource configurations ofthe UE are configured on at least two BWPs of the UE, and serving cellsthat are of the UE and in which the at least two BWPs are located are asame serving cell or different serving cells. In the foregoing technicalsolution, the SR resource configurations of the UE may be configured ondifferent BWPs, to avoid a problem that when a single BWP isunavailable, the UE cannot transmit an SR associated with any logicalchannel, thereby improving reliability.

In some embodiments of the first aspect or the second aspect, before theUE activates the first BWP, if a serving cell in which the first BWP islocated is not activated, the UE activates the serving cell.

In some embodiments of the first aspect or the second aspect, that theUE activates the first BWP is specifically that the user equipmentactivates the first BWP and deactivates a second BWP activated beforethe first BWP is activated.

In some embodiments of the second aspect, the SR configuration includesSR-prohibit timer duration, the UE sets an SR-prohibit timer for the SRconfiguration, the SR-prohibit timer is configured to prohibit, during arunning period of the SR-prohibit timer, the UE from transmitting an SRon the physical resource indicated by the SR resource configuration,duration for which the SR-prohibit timer runs after being started eachtime is the SR-prohibit timer duration, and the UE transmits, on thefirst BWP, the SR associated with the first logical channel, and startsthe SR-prohibit timer.

In some embodiments of the first aspect or the second aspect, aftertransmitting, on the first BWP, the SR associated with the first logicalchannel, the UE returns to the second BWP on which the UE works beforethe first BWP is activated, to continue to perform a transmission taskon the second BWP, thereby improving network resource utilization.

In some embodiments of the first aspect or the second aspect, after theUE returns to the second BWP activated before the first BWP isactivated, the UE activates the first BWP if the SR is triggered and notcanceled and the SR-prohibit timer does not run, and the UE transmits,on the first BWP, the SR associated with the first logical channel, andstarts the SR-prohibit timer.

In some embodiments of the first aspect or the second aspect, anoccasion on which the UE activates the first BWP is as follows: The SRassociated with the first logical channel is triggered and not canceled,and the SR-prohibit timer does not run. Because the UE can send the SRassociated with the first logical channel only when “the SR associatedwith the first logical channel is triggered and not canceled, and theSR-prohibit timer does not run”, the UE activates the first BWP onlywhen the condition is met, to avoid a situation in which the first BWPis activated excessively early, but the SR associated with the firstlogical channel cannot be sent on the first BWP, thereby reducing powerconsumption of the UE, and avoiding a network transmission resourcewaste.

In some embodiments of the first aspect or the second aspect, the userequipment deactivates the first BWP after transmitting the SR on thefirst BWP, thereby reducing power consumption of the UE.

In some embodiments of the first aspect or the second aspect, after theUE activates the first BWP, the user equipment may keep the first BWPbeing activated, until any one of the following conditions is met:control signaling sent by the network device for deactivating the firstBWP is received; the UE can activate only one BWP in a same servingcell, and receives control signaling sent by the network device foractivating another BWP in the serving cell in which the first BWP islocated; a timer configured to control deactivation of the first BWPexpires, where the timer may be started when no data or signaling istransmitted on the first BWP; the UE releases the physical resource thatis on the first BWP, that is indicated by the SR resource configurationassociated with the SR configuration, and that is used to transmit theSR; and the SR associated with the first logical channel is canceled. Inthe foregoing technical solution, after activating the first BWP, the UEmay keep an activated state of the first BWP, so that when the SRassociated with the first logical channel is not canceled and theSR-prohibit timer does not run, the UE may continue to send, on thefirst BWP, the SR associated with the first logical channel, to avoidactivating the first BWP again after the first BWP is deactivated. Inaddition, when any one of the foregoing conditions is met, the UE candeactivate the first BWP, so that a network resource waste and powerconsumption of the UE are reduced, or normal running of a network isensured.

According to a third aspect, this application provides a schedulingrequest SR configuration method, including: determining, by a networkdevice, control signaling, where the control signaling is used toconfigure, for UE, an SR configuration associated with at least onelogical channel and at least two SR resource configurations associatedwith the SR configuration, and the SR resource configurations indicatephysical resources used to transmit an SR associated with the at leastone logical channel; and sending, by the network device, the controlsignaling to the UE.

In some embodiments of the first aspect or the third aspect, the controlsignaling includes first control signaling and second control signaling,the first control signaling is used to configure, for the UE, the SRconfiguration associated with the at least one logical channel and afirst part of SR resource configurations in the at least two SR resourceconfigurations associated with the SR configuration, and the secondcontrol signaling is used to configure, for the UE, a second part of SRresource configurations in the at least two SR resource configurationsassociated with the SR configuration. In the foregoing technicalsolution, the network device may send a plurality of pieces of controlsignaling to the UE, and the UE updates, based on the plurality ofpieces of control signaling, the SR resource configurations associatedwith the logical channel. With reference to a configuration manner 2,the network device may instruct, by using the control signaling, the UEto update the SR resource configurations associated with the SRconfiguration. Therefore, a manner of adjusting the SR resourceconfigurations associated with the SR configuration is flexible, andefficiency is relatively high.

In theforegoing technical solution, physical resources for transmitting an SRassociated with a logical channel are configured on a plurality of BWPsof the UE, so that when one of the plurality of BWPs is not activated orthe physical resource on the BWP is unavailable, an SR may betransmitted by using a physical resource indicated by the SR resourceconfiguration configured on another BWP in the plurality of BWPs.Therefore, the UE can transmit the SR in a timelier manner, therebyreducing an SR transmission latency.

A bandwidth part (BWP) is as follows: Referring to FIG. 1 , to enable UEhaving a lowest bandwidth capability in all UEs to work on a broadbandcarrier, the broadband carrier is divided into a plurality of smallbandwidth parts, and each bandwidth part is referred to as a BWP.

A scheduling request (SR) configuration is associated with a logicalchannel, and is used to indicate a physical resource for sending an SRassociated with the logical channel. In the embodiments of the presentdisclosure, a concept of the SR configuration may have the followingcases: (1) The SR configuration includes an identifier of the SRconfiguration, an SR-prohibit timer, and a maximum quantity of SRtransmission times, and also includes a parameter used to determine alocation of a physical resource used to transmit an SR. In this case,one logical channel is associated with/mapped to at least one SRconfiguration. (2) The SR configuration includes an identifier of the SRconfiguration, an SR-prohibit timer, and a maximum quantity of SRtransmission times, but includes no parameter used to determine alocation of a physical resource used to transmit an SR. A parameter usedto determine a location of a physical resource used to transmit an SR isincluded in another SR-related configuration. For example, theSR-related configuration may be an SR resource configuration. In thiscase, one logical channel is associated with/mapped to at least one SRconfiguration, and one SR configuration is associated with/mapped to atleast one SR resource configuration.

An SR resource configuration is as follows: A configuration thatspecifically includes a parameter used to determine a location of aphysical resource used to transmit an SR is referred to as the SRresource configuration.

FIG. 2 is a schematic diagram of a communications system according to anembodiment of the present disclosure. The communications system includesa network device and a plurality of UEs. With reference to thecommunications system shown in FIG. 1 , an embodiment of the presentdisclosure provides an SR configuration method. Referring to FIG. 3 ,the method includes the following steps.

Step 11: The network device sends control signaling to UE, where thecontrol signaling is used to configure, for the UE,

an SR configuration associated with at least one logical channel; and

an SR resource configuration associated with the SR configuration.

In this embodiment of the present disclosure, the SR configurationassociated with the at least one logical channel and the SR resourceconfiguration associated with the SR configuration may include thefollowing implementations:

In a configuration manner 1, at least one logical channel is associatedwith one SR configuration, and the SR configuration is associated withone SR resource configuration.

In a configuration manner 2, at least one logical channel is associatedwith one SR configuration, and the SR configuration is associated withat least two SR resource configurations.

In a configuration manner 3, at least one logical channel is associatedwith at least two SR configurations, and each SR configuration isassociated with one SR resource configuration. When the at least onelogical channel is two or more logical channels, each of the two or morelogical channels is associated with the at least two SR configurations.In other words, a physical resource indicated by the SR resourceconfiguration associated with each SR configuration may be used totransmit an SR associated with any one of the at least one logicalchannel.

To facilitate description, for the configuration manner 1, in thefollowing content of this embodiment of the present disclosure, an “SRresource configuration associated with an SR configuration associatedwith a logical channel” is referred to as an “SR resource configurationassociated with a logical channel” for short. For the configurationmanner 2 and the configuration manner 3, in the following content ofthis embodiment of the present disclosure, “at least two SR resourceconfigurations associated with an SR configuration associated with alogical channel” and a “set of SR resource configurations associatedwith each of at least two SR configurations associated with a logicalchannel” are referred to as “at least two SR resource configurationsassociated with a logical channel” for short.

When the at least one logical channel is two or more logical channels,the two or more logical channels may have a same QoS requirement. A sameSR resource configuration is associated with the two or more logicalchannels, so that the UE transmits, based on a physical resourceindicated by the SR resource configuration associated with the two ormore logical channels, an SR associated with one of the two or morelogical channels. When receiving the SR, the network device maydetermine, based on a location of the physical resource for transmittingthe SR, a logical channel to which the SR resource configurationcorresponding to the location of the physical resource is mapped, andthen allocate, to the UE based on a mapping relationship between thelogical channel and a physical transmission parameter set, an uplinktransmission resource meeting the physical transmission parameter set,so that the uplink transmission resource can meet the QoS requirement ofthe at least one logical channel of the UE. The physical transmissionparameter set may include at least one of a subcarrier spacing, a cyclicprefix length, physical uplink shared channel (PUSCH) transmissionduration, a time interval between control signaling for scheduling PUSCHtransmission and a PUSCH transmission resource, and an available servingcell.

In a communications network, the UE may be configured in only one of theforegoing three configuration manners. Alternatively, in acommunications network, any two or all of the foregoing threeconfiguration manners may be implemented at the same time, and thenetwork device may select a proper configuration manner based ondifferent types/communication requirements of UEs. For example, theconfiguration manner 2 may be used for a mobile terminal, and at leasttwo SR resource configurations are configured for a logical channel ofthe mobile terminal, so that when a physical resource indicated by oneof the at least two SR resource configurations is unavailable or hasrelatively poor transmission quality because the mobile terminal moves,the mobile terminal can transmit an SR based on a physical resourceindicated by another SR resource configuration configured for thelogical channel. Therefore, the mobile terminal can transmit the SR in atimely manner. For another example, a smart home device usually does notmove, and therefore one SR resource configuration may be configured forthe smart home device in the configuration manner 1, to save a physicalresource for transmitting an SR.

Step 12: The UE receives the control signaling, associates the SRconfiguration with the logical channel based on the control signaling,and associates the SR resource configuration with the SR configurationbased on the control signaling. In some implementations, the UE maystore the SR configuration (file) and the SR resource configuration(file), and a configuration (file) of the logical channel may include anidentifier/a parameter pointing to the SR configuration associated withthe logical channel, or the SR configuration (file) may include anidentifier/a parameter pointing to the at least one logical channelassociated with the SR configuration. Likewise, the SR configuration(file) includes an identifier/a parameter pointing to the SR resourceconfiguration associated with the SR configuration, or the SR resourceconfiguration (file) includes an identifier/a parameter pointing to theSR configuration associated with the SR resource configuration. In someother embodiments, the UE may create or update, based on the controlsignaling, a list of physical resources for transmitting an SR of thelogical channel. Table 1 is a possible instance of the list.

TABLE 1 Logical channel SR configuration SR resource configuration LCH 1and LCH 2 SR configuration 1 SR resource configurations 1 and 2 LCH 3 SRconfiguration 2 SR resource configuration 3 LCH 4 and LCH 5 SRconfiguration 3 SR resource configuration 4 SR configuration 4 SRresource configuration 5 . . . . . . . . .

In Table 1, the second row corresponds to the configuration manner 2,the third row corresponds to the configuration manner 1, and the fourthrow corresponds to the configuration manner 3.

Step 13: The UE transmits, based on a physical resource indicated by theSR resource configuration associated with the SR configurationassociated with the at least one logical channel, an SR associated withone of the at least one logical channel.

When the configuration manner 2 is implemented, for a logical channel ofthe UE, the UE transmits, based on a physical resource indicated by oneof at least two SR resource configurations associated with an SRconfiguration associated with the logical channel, an SR associated withthe logical channel. When the configuration manner 3 is implemented, fora logical channel of the UE, the UE transmits, based on a physicalresource indicated by an SR resource configuration associated with oneof at least two SR configurations associated with the logical channel,an SR associated with the logical channel.

In a technical solution corresponding to the configuration manner 1, aplurality of logical channels of the UE that have a same QoS requirementmay be associated with a same SR configuration, so that when receivingan SR transmitted based on a physical resource indicated by the SRconfiguration, the network device allocates an uplink transmissionresource matching a location of the physical resource, to meet the QoSrequirement of the logical channels. In a technical solutioncorresponding to the configuration manner 2 or the configuration manner3, the at least one logical channel may be associated with at least twoSR resource configurations, so that when a physical resource indicatedby one of the SR resource configurations is unavailable, the UE cantransmit an SR by using a physical resource indicated by anotherassociated SR resource configuration. Therefore, the UE can transmit theSR in a timelier manner, thereby reducing an SR transmission latency. Inaddition, when the foregoing plurality of configuration manners areimplemented in a same network, for requirements of different UEs, aphysical resource for transmitting an SR associated with a logicalchannel can be flexibly configured for the UEs, thereby improvingnetwork resource utilization.

In an optional manner, with reference to the configuration manner 2 or3, the network device may send a plurality of pieces of controlsignaling to associate at least two SR resource configurations with theat least one logical channel.

For example, with reference to the configuration manner 2, in step 12,the control signaling includes first control signaling and secondcontrol signaling, and the UE receives the first control signaling sentby the network device. The first control signaling is used to configure,for the UE, the SR configuration associated with the at least onelogical channel and a first part of SR resource configurationsassociated with the SR configuration. The first part of SR resourceconfigurations may be one or more SR resource configurations. Then, theUE receives the second control signaling sent by the network device. Thesecond control signaling is used to configure, for the UE, a second partof SR resource configurations associated with the SR configuration. Thesecond part of SR resource configurations may be one or more SR resourceconfigurations. In some embodiments, in response to the second controlsignaling, the UE adds the second part of SR resource configurations tothe SR resource configuration associated with the SR configuration. Inother words, the UE associates both the first part of SR resourceconfigurations and the second part of SR resource configurations withthe SR configuration. In some other embodiments, in response to thesecond control signaling, the UE replaces the first part of SR resourceconfigurations and an associated SR resource configuration with thesecond part of SR resource configurations. In other words, the UEcancels an association between the first part of SR resourceconfigurations and the SR configuration, and associates the second partof SR resource configurations with the SR configuration.

For another example, with reference to the configuration manner 3, instep 12, the control signaling includes third control signaling andfourth control signaling, and the UE receives the third controlsignaling sent by the network device. The third control signaling isused to configure, for the UE, a first part of SR configurationsassociated with the at least one logical channel and an SR resourceconfiguration associated with each of the first part of SRconfigurations. The first part of SR configurations may be one or moreSR configurations. Then, the UE receives second control signaling sentby the network device. The second control signaling is used toconfigure, for the UE, a second part of SR configurations associatedwith the at least one logical channel and an SR resource configurationassociated with each of the second part of SR configurations. The secondpart of SR configurations may be one or more SR configurations.

In the foregoing technical solution, the network device may send theplurality of pieces of control signaling to the UE, and the UE updates,based on the plurality of pieces of control signaling, the SR resourceconfigurations associated with the logical channel. With reference tothe configuration manner 2, the network device may instruct, by usingthe control signaling, the UE to update the SR resource configurationsassociated with the SR configuration. Therefore, a manner of adjustingthe SR resource configurations associated with the SR configuration isflexible, and efficiency is relatively high.

In an optional manner, in step 12, the control signaling may further beused to configure a configuration of the at least one logical channelfor the UE. In this technical solution, the network device mayconfigure, together for the UE, the logical channel, the SRconfiguration associated with the logical channel, and the SR resourceconfiguration associated with the SR. Therefore, efficiency isrelatively high.

In this embodiment of the present disclosure, a BWP is configured in aserving cell, and the SR resource configuration may be configured on theBWP, in other words, the physical resource indicated by the SR resourceconfiguration is located on the BWP. There may be a plurality of typesof correspondences between an SR resource configuration associated witha logical channel and a BWP configured by the network device for the UE,including the following correspondences.

In a correspondence 1, for the configuration manner 1, all SR resourceconfigurations of the UE are configured on a same BWP, to be specific,physical resources for transmitting an SR associated with any logicalchannel of the UE are all located on the BWP. The BWP may be a defaultBWP of the UE. For example, referring to FIG. 4 a , the network deviceallocates one serving cell to the UE, a plurality of BWPs are configuredin the serving cell, and all the SR resource configurations of the UEare configured on one BWP of the serving cell. For another example,referring to FIG. 4 b , the network device allocates a plurality ofserving cells to the UE, and all the SR resource configurations of theUE are configured on one BWP of one of the serving cells. The servingcell may have a plurality of BWPs. Alternatively, the serving cell hasonly one BWP, and the BWP corresponds to all bandwidth of the servingcell. The latter case may also be understood as follows: All the SRresource configurations of the UE are configured on one serving cell,and no BWP is configured in the serving cell.

In a solution of the correspondence 1, all the SR resourceconfigurations of the UE are configured on one BWP, so that the UEquickly locates a physical resource for transmitting an SR.

In a correspondence 2, for the configuration manner 1, SR resourceconfigurations of the UE are configured on at least two BWPs of the UE.This may include the following cases: (1) Referring to FIG. 4 c , thenetwork device allocates one serving cell to the UE, a plurality of BWPsare configured in the serving cell, and SR resource configurations areconfigured on at least two BWPs. (2) Referring to FIG. 4 d , the networkdevice allocates a plurality of serving cells to the UE, an SR resourceconfiguration is configured in only one of the serving cells, and SRresource configurations are configured on at least two BWPs of theserving cell. (3) Referring to FIG. 4 e , the network device allocates aplurality of serving cells to the UE, the BWPs are configured in atleast two serving cells, only one BWP may be configured or a pluralityof BWPs may be configured in one of the at least two serving cells (orno BWP division is performed in the serving cell, such as a serving cell2), and an SR resource configuration may be configured on one or more ofthe plurality of BWPs.

In a solution of the correspondence 2, the SR resource configurations ofthe UE may be configured on different BWPs, to avoid a problem that whena single BWP is unavailable, the UE cannot transmit an SR associatedwith any logical channel, thereby improving reliability.

In a correspondence 3, for the configuration manner 2 or theconfiguration manner 3, the at least two SR resource configurationsassociated with the at least one logical channel are respectivelyconfigured on different BWPs, and each SR resource configurationindicates a physical resource for transmitting an SR on a BWP on whichthe SR resource configuration is configured. Optionally, referring toFIG. 4 f (one serving cell is allocated to the UE) and FIG. 4 g (aplurality of serving cells are allocated to the UE), a plurality of BWPson which the at least two SR resource configurations are configured maybelong to a same serving cell. Alternatively, referring to FIG. 4 h ,the network device allocates two serving cells to the UE, a logicalchannel 1 and a logical channel 2 are associated with an SRconfiguration 1, the SR configuration 1 is associated with an SRresource configuration 1 and an SR resource configuration 2, the SRresource configuration 1 is configured on a BWP 1 of a serving cell 1,and the SR resource configuration 2 is configured in a serving cell 2(no BWP division is performed in the serving cell 2).

In a solution of the correspondence 3, physical resources fortransmitting an SR associated with a logical channel are configured on aplurality of BWPs of the UE, so that when one of the plurality of BWPsis not activated or the physical resource on the BWP is unavailable, anSR may be transmitted by using a physical resource indicated by the SRresource configuration configured on another BWP in the plurality ofBWPs. Therefore, the UE can transmit the SR in a timelier manner,thereby reducing an SR transmission latency.

In a correspondence 4, with reference to the correspondence 3, one ofthe at least two SR resource configurations is configured on each BWPallocated by the network device to the UE. The correspondence may alsobe described as follows: The network device allocates N BWPs to the UE,the network device configures N associated SR resource configurationsfor the at least one logical channel, the N SR resource configurationsare respectively configured on the N BWPs, and one SR resourceconfiguration is configured on each BWP.

In a solution of the correspondence 4, when working on any BWP, the UEmay transmit an SR by using a physical resource indicated by an SRresource configuration on the BWP on which the UE currently works, sothat reliability is improved, and the SR can be transmitted in a timelymanner.

Optionally, in the correspondences 1 to 4, a serving cell to which a BWPon which an SR resource configuration is configured belongs is a servingcell in which a physical uplink control channel is configured.

In an optional manner, with reference to the configuration manner 2, instep 12, the SR configuration configured for the UE by using the controlsignaling includes a maximum quantity of SR transmission times. The UEsets, for the SR configuration based on the maximum quantity of SRtransmission times, a variable for recording a quantity of SRtransmission times, adds one to a value of the variable aftertransmitting an SR on a physical resource indicated by any one of the atleast two SR resource configurations, and after the value of thevariable reaches the maximum quantity of SR transmission times, releasesphysical resources indicated by the at least two SR resourceconfigurations associated with the SR configuration.

In the foregoing technical solution, the variable is set for the SRconfiguration associated with the at least one logical channel. Thisfacilitates unified management on transmission behavior of an SRassociated with the logical channel, and improves efficiency of managingthe transmission behavior of the SR associated with the logical channel.

In an optional manner, with reference to the configuration manner 3, instep 12, all SR configurations configured for the UE by using thecontrol signaling include a same maximum quantity of SR transmissiontimes. The UE sets, for each SR configuration based on the maximumquantity of SR transmission times, a variable for recording a quantityof SR transmission times, to record a quantity of times of SRtransmission on a physical resource indicated by an SR resourceconfiguration associated with the SR configuration. After transmittingan SR on a physical resource indicated by an SR resource configurationassociated with an SR configuration, the UE adds one to a value of avariable that is set for the SR configuration, and after the value ofthe variable reaches the maximum quantity of SR transmission times,releases the physical resource indicated by the SR resourceconfiguration associated with the SR configuration.

In the foregoing technical solution, different variables are set fordifferent SR configurations. This facilitates precise management on SRtransmission behavior on a physical resource indicated by each SRresource configuration.

In an optional manner, with reference to the configuration manner 3, instep 12, each SR configuration configured for the UE by using thecontrol signaling includes an independent maximum quantity of SRtransmission times. The UE sets, for a corresponding SR configuration inthe plurality of SR configurations based on the maximum quantity of SRtransmission times, a variable for recording a quantity of SRtransmission times, to record a quantity of times of SR transmission ona physical resource indicated by an SR resource configuration associatedwith the SR configuration. After transmitting an SR on a physicalresource indicated by an SR resource configuration associated with an SRconfiguration, the UE adds one to a value of a variable that is set forthe SR configuration, and after the value of the variable reaches themaximum quantity of SR transmission times, releases the physicalresource indicated by the SR resource configuration associated with theSR configuration.

In the foregoing technical solution, different variables are set fordifferent SR configurations. This facilitates precise management on SRtransmission behavior on a physical resource indicated by each SRresource configuration.

In an optional manner, with reference to the configuration manner 1 orthe configuration manner 2, the SR configuration configured for the UEby using the control signaling includes SR-prohibit timer duration. TheUE sets an SR-prohibit timer for the SR configuration based on theSR-prohibit timer duration, and starts the SR-prohibit timer aftertransmitting an SR on a physical resource indicated by an SR resourceconfiguration associated with the SR configuration. The SR-prohibittimer is configured to prohibit, during a running period of theSR-prohibit timer, the UE from transmitting an SR on the physicalresource indicated by the SR resource configuration associated with theSR configuration, and duration for which the SR-prohibit timer runsafter being started each time is the SR-prohibit timer duration. Withreference to the configuration manner 2, the UE starts the SR-prohibittimer after transmitting an SR on a physical resource indicated by anyone of the at least two SR resource configurations. The SR-prohibittimer is configured to prohibit, during the running period of theSR-prohibit timer, the UE from transmitting an SR on a physical resourceindicated by any one of the at least two SR resource configurations.

In the foregoing technical solution, the UE sets the SR-prohibit timerfor the SR configuration. This can avoid a transmission resource wastecaused when an SR associated with a logical channel is resent onlybecause the UE receives no uplink resource grant due to a normaltransmission latency after the network device has normally responded toa previously sent SR, and can also prevent the network device fromreceiving a repeated SR.

In an optional manner, with reference to the configuration manner 3, aplurality of SR configurations associated with the at least one logicalchannel of the UE include same SR-prohibit timer duration, or only oneof the SR configurations includes SR-prohibit timer duration, or theplurality of SR configurations include no SR-prohibit timer duration,but include an identifier of an SR configuration group. The controlsignaling is further used to associate the SR configuration group withthe at least one logical channel, and the SR configuration groupincludes the SR-prohibit timer duration. The UE sets an SR-prohibittimer for the plurality of SR configurations based on the SR-prohibittimer duration, and starts the SR-prohibit timer after transmitting anSR on a physical resource indicated by an SR resource configurationassociated with any one of the plurality of SR configurations. TheSR-prohibit timer is configured to prohibit, during a running period ofthe SR-prohibit timer, the UE from transmitting an SR on a physicalresource indicated by an SR resource configuration associated with anyone of the plurality of SR configurations, and duration for which theSR-prohibit timer runs after being started each time is the SR-prohibittimer duration.

In the foregoing technical solution, the UE sets the same SR-prohibittimer for the plurality of SR configurations associated with the atleast one logical channel. This can avoid a transmission resource wastecaused when an SR associated with a logical channel is resent onlybecause the UE receives no uplink resource grant due to a normaltransmission latency after the network device has normally responded toa previously sent SR, and can also prevent the network device fromreceiving a repeated SR.

In an optional manner, with reference to the configuration manner 3, aplurality of SR configurations associated with the at least one logicalchannel of the UE include same SR-prohibit timer duration, or only oneof the SR configurations includes SR-prohibit timer duration, or theplurality of SR configurations include no SR-prohibit timer duration,but include an identifier of an SR configuration group. The controlsignaling is further used to associate the SR configuration group withthe at least one logical channel, and the SR configuration groupincludes the SR-prohibit timer duration. The UE sets an SR-prohibittimer for each of the plurality of SR configurations based on theSR-prohibit timer duration, and starts the SR-prohibit timer aftertransmitting an SR on a physical resource indicated by an SR resourceconfiguration associated with the SR configuration. The SR-prohibittimer is configured to prohibit, during a running period of theSR-prohibit timer, the UE from transmitting an SR on the physicalresource indicated by the SR resource configuration associated with theSR configuration, and duration for which the SR-prohibit timer runsafter being started each time is the SR-prohibit timer duration.

In the foregoing technical solution, the UE sets the independentSR-prohibit timer for each of the plurality of SR configurationsassociated with the at least one logical channel, so that when sendingan SR on the physical resource indicated by the SR resourceconfiguration associated with each SR configuration, the UE may not beaffected by behavior of sending an SR on a physical resource indicatedby an SR resource configuration associated with another SRconfiguration.

In an optional manner, with reference to the configuration manner 3, aplurality of SR configurations associated with the at least one logicalchannel of the UE include independent SR-prohibit timer duration. The UEsets an SR-prohibit timer for each corresponding SR configuration in theplurality of SR configurations based on the SR-prohibit timer duration,and starts the SR-prohibit timer after transmitting an SR on a physicalresource indicated by an SR resource configuration associated with theSR configuration. The SR-prohibit timer is configured to prohibit,during a running period of the SR-prohibit timer, the UE fromtransmitting an SR on the physical resource indicated by the SR resourceconfiguration associated with the SR configuration, and duration forwhich the SR-prohibit timer runs after being started each time is theSR-prohibit timer duration.

In the foregoing technical solution, the UE sets the independentSR-prohibit timer for each of the plurality of SR configurationsassociated with the at least one logical channel, so that when sendingan SR on the physical resource indicated by the SR resourceconfiguration associated with each SR configuration, the UE may not beaffected by behavior of sending an SR on a physical resource indicatedby an SR resource configuration associated with another SRconfiguration.

The following continues to describe several possible implementations ofa method used by the UE to send an SR.

In an implementation 1, with reference to the configuration manner 2 orthe configuration manner 3, referring to FIG. 5 , that the UE sends anSR includes the following steps.

Step 21: If an SR associated with a first logical channel in the atleast one logical channel is triggered and not canceled, the UEdetermines that a first SR resource configuration in at least two SRresource configurations associated with the first logical channel isconfigured on an activated first BWP.

With reference to the configuration manner 2, a process in which the UEdetermines that a first SR resource configuration in at least two SRresource configurations associated with the first logical channel isconfigured on an activated first BWP may be as follows: The UEdetermines that the first logical channel is associated with the SRconfiguration, determines that SR resource configurations associatedwith the SR configuration are the at least two SR resourceconfigurations, and determines that the first SR resource configurationin the at least two SR resource configurations is configured on theactivated first BWP.

With reference to the configuration manner 3, a process in which the UEdetermines that a first SR resource configuration in at least two SRresource configurations associated with the first logical channel isconfigured on an activated first BWP may be as follows: The UEdetermines that the first logical channel is associated with the atleast two SR configurations, determines SR resource configurationsrespectively associated with the at least two SR configurations, anddetermines that the first SR resource configuration associated with afirst SR configuration in the at least two SR configurations isconfigured on the activated first BWP.

Step 22: For each time unit, if the user equipment has a physicalresource indicated by the first SR resource configuration in the currenttime unit and an SR-prohibit timer that is set for the SR configurationdoes not run, the UE transmits, on the physical resource indicated bythe first SR resource configuration, the SR associated with the firstlogical channel, and starts the SR-prohibit timer.

In the foregoing technical solution, when the at least two SR resourceconfigurations associated with the first logical channel are configuredon different BWPs, the UE sends the SR by using the physical resourceindicated by the first SR resource configuration configured on theactivated first BWP, to ensure that the UE can transmit the SR in atimely manner.

Optionally, with reference to the implementation 1, referring to FIG. 6, after step 22, the method further includes the following steps.

Step 23: If a BWP activated by the UE changes from the first BWP to asecond BWP and the SR associated with the first logical channel is notcanceled, the user equipment determines that a second SR resourceconfiguration associated with the first logical channel is configured onthe activated second BWP. In some embodiments, the UE may change theactivated BWP from the first BWP to the second BWP according to aninstruction of the network device. In some other embodiments, the UE mayautonomously change the activated BWP from the first BWP to the secondBWP. For example, when the physical resource indicated by the first SRresource configuration on the first BWP has been released, the UE maychange the activated BWP from the first BWP to the second BWP.

Step 24: For each time unit, if the user equipment has a physicalresource indicated by the second SR resource configuration in thecurrent time unit and the SR-prohibit timer that is set for the SRconfiguration does not run, the UE transmits, on the physical resourceindicated by the second SR resource configuration, the SR associatedwith the first logical channel, and starts the SR-prohibit timer.

In the foregoing technical solution, when the BWP activated by the UEchanges and the SR associated with the first logical channel is notcanceled, the UE may continue to send, on the activated second BWP afterthe change, the SR by using the physical resource indicated by the SRresource configuration associated with the first logical channel, sothat the network device can allocate an uplink transmission resource tothe first logical channel in a timely manner.

Optionally, in the implementation 1, the UE can activate only one BWP.Alternatively, the UE can activate only one BWP in one serving cell, butcan activate two or more serving cells at the same time. Alternatively,the UE can activate two or more BWPs in one serving cell.

In an implementation 2, with reference to the configuration manner 2 orthe configuration manner 3, referring to FIG. 7 , that the UE sends anSR includes the following steps.

Step 31: If an SR associated with a first logical channel in the atleast one logical channel is triggered and not canceled, the UEdetermines at least two SR resource configurations associated with thefirst logical channel, and determines that a third SR resourceconfiguration in the at least two SR resource configurations isconfigured on an activated third BWP, and a fourth SR resourceconfiguration in the at least two SR resource configurations isconfigured on an activated fourth BWP. For an implementation in which“the UE determines at least two SR resource configurations associatedwith the first logical channel” in the configuration manner 2 or theconfiguration manner 3, refer to the description in step 21.

Step 32: For each time unit, if an SR-prohibit timer that is set for theSR configuration does not run and the user equipment has a physicalresource indicated by the third SR resource configuration or the fourthSR resource configuration in the current time unit, the UE transmits, onthe physical resource, the SR associated with the first logical channel,and starts the SR-prohibit timer.

A possible implementation process of step 32 is as follows: The UEsends, by using the physical resource indicated by the third resourceconfiguration, the SR associated with the first logical channel, andstarts the SR-prohibit timer. After the SR-prohibit timer expires, ifthe SR associated with the first logical channel is not canceled, andthe UE has no physical resource indicated by the third SR resourceconfiguration, but has the physical resource indicated by the fourth SRresource configuration, the UE may send the SR by using the physicalresource indicated by the fourth SR resource configuration, and startthe timer.

In the foregoing technical solution, when the SR-prohibit timer does notrun, the UE may transmit the SR by using a currently obtained physicalresource for transmitting the SR associated with the first logicalchannel, and is not limited to transmitting the SR resource on aphysical resource indicated by an SR resource configuration on aspecific BWP. Therefore, utilization of a physical resource fortransmitting the SR can be improved, and the SR can be transmitted in atimely manner, so that a time consumed by the UE to wait for an uplinkresource grant is reduced.

In an implementation 3, with reference to the configuration manner 1,referring to FIG. 8 , that the UE sends an SR includes the followingsteps.

Step 41: The UE activates a first BWP if the UE has an SR that isassociated with a first logical channel in the at least one logicalchannel and that is triggered and not canceled, the SR resourceconfiguration associated with the first logical channel is configured onthe first BWP, and the first BWP is not activated.

Step 42: The UE transmits, on a physical resource indicated by the SRresource configuration, the SR associated with the first logicalchannel, and starts an SR-prohibit timer.

In the foregoing technical solution, the UE may actively activate thefirst BWP when the first BWP on which the physical resource fortransmitting the SR associated with the first logical channel isconfigured is not activated, and the SR associated with the firstlogical channel needs to be sent, and send the SR by using the physicalresource indicated by the SR resource configuration that is on the firstBWP and that is associated with the first logical channel. Therefore,the SR is transmitted in a timely manner, so that a time consumed by theUE to wait for an uplink resource grant is reduced.

In an implementation 4, with reference to the configuration manner 2 orthe configuration manner 3, referring to FIG. 9 , that the UE sends anSR includes the following steps.

Step 51: If an SR associated with a first logical channel in the atleast one logical channel is triggered and not canceled, and none ofBWPs on which at least two SR resource configurations associated withthe first logical channel are configured is activated, the UE activatesa first BWP on which a first SR resource configuration in the at leasttwo SR resource configurations is configured.

Step 52: For each time unit, if the user equipment has a physicalresource indicated by the first SR resource configuration in the currenttime unit and an SR-prohibit timer that is set for the SR configurationdoes not run, the UE transmits, on the physical resource indicated bythe first SR resource configuration, the SR associated with the firstlogical channel, and starts the SR-prohibit timer.

In the foregoing technical solution, the UE may actively activate a BWP,namely, the first BWP, in a plurality of BWPs when the plurality of BWPson which a physical resource for transmitting the SR associated with thefirst logical channel is configured are not activated, and the SRassociated with the first logical channel needs to be sent, and send theSR by using the physical resource indicated by the SR resourceconfiguration that is on the first BWP and that is associated with thefirst logical channel. Therefore, the SR is transmitted in a timelymanner, so that a time consumed by the UE to wait for an uplink resourcegrant is reduced.

Optionally, with reference to the implementation 4, the UE maydetermine, in the following manner, which one of a plurality of logicalchannels on which an SR resource configuration associated with the firstlogical channel is configured is to be activated, and details are asfollows: If the UE determines that an SR transmission occasion indicatedby the first SR resource configuration configured on the first BWP isearlier than an SR transmission occasion indicated by any SR resourceconfiguration other than the first SR resource configuration in the atleast two SR resource configurations, the UE determines to activate thefirst BWP.

In the foregoing technical solution, when none of the BWPs on which theat least two SR resource configurations associated with the firstlogical channel are configured is activated, the UE activates the firstBWP on which the physical resource that can be earliest used to transmitthe SR associated with the first logical channel is configured, totransmit the SR in a timely manner, thereby reducing a time consumed bythe UE to wait for an uplink resource grant.

Optionally, with reference to the implementation 3 or the implementation4, before the UE activates the first BWP, if a serving cell in which thefirst BWP is located is not activated, the UE activates the servingcell, so that the UE can further activate the first BWP. In someembodiments, the serving cell to which the first BWP belongs and thefirst BWP are simultaneously activated. The embodiments of the presentdisclosure are intended to protect this solution.

Optionally, with reference to the implementation 3 or the implementation4, after the UE activates the first BWP, the user equipment may keep thefirst BWP being activated, until any one of the following conditions ismet:

a. control signaling sent by the network device for deactivating thefirst BWP is received;

b. the UE can activate only one BWP in a same serving cell, and receivescontrol signaling sent by the network device for activating another BWPin the serving cell in which the first BWP is located;

c. a timer configured to control deactivation of the first BWP expires,where the timer may be started when no data or signaling is transmittedon the first BWP;

d. the UE releases the physical resource that is on the first BWP, thatis indicated by the SR resource configuration associated with the SRconfiguration, and that is used to transmit the SR; and

e. the SR associated with the first logical channel is canceled.

In the foregoing technical solution, after activating the first BWP, theUE may keep an activated state of the first BWP, so that when the SRassociated with the first logical channel is not canceled and theSR-prohibit timer does not run, the UE may continue to send, on thefirst BWP, the SR associated with the first logical channel, to avoidactivating the first BWP again after the first BWP is deactivated. Inaddition, when any one of the foregoing conditions is met, the UE candeactivate the first BWP, so that a network resource waste and powerconsumption of the UE are reduced, or normal running of a network isensured.

Optionally, with reference to the implementation 3 or the implementation4, when activating the first BWP, the UE deactivates a second BWPactivated before the first BWP is activated. In some variant solutions,the UE first deactivates the second BWP, and then activates the firstBWP. In some other variant solutions, the UE first activates the firstBWP, and then deactivates the second BWP. The embodiments of the presentdisclosure are intended to protect these variations.

Optionally, with reference to the implementation 3 or the implementation4, after transmitting, on the first BWP, the SR associated with thefirst logical channel, the UE returns to the second BWP on which the UEworks before the first BWP is activated. A purpose for which the UEworks on the first BWP is to transmit the SR associated with the firstlogical channel. After the SR is sent on the first BWP, the SR-prohibittimer is started. Because the UE needs to continue to send data and/orreceive data on the second BWP, the UE returns to the second BWP onwhich the UE previously works, to continue to perform a transmissiontask on the second BWP, thereby improving network resource utilization.

Optionally, with reference to the implementation 3 or the implementation4, after transmitting, on the first BWP, the SR associated with thefirst logical channel, the UE deactivates the first BWP. A purpose forwhich the UE works on the first BWP is to transmit the SR associatedwith the first logical channel. After the SR is sent on the first BWP,the SR-prohibit timer is started. Because the UE has no transmissiontask on the first BWP, the UE may deactivate the first BWP, therebyreducing power consumption of the UE.

Optionally, with reference to the implementation 3 or the implementation4, after transmitting, on the first BWP, the SR associated with thefirst logical channel, the UE deactivates the first BWP, and returns tothe second BWP on which the UE works before the first BWP is activated,to improve network resource utilization and reduce power consumption ofthe UE.

Optionally, with reference to the implementation 3 or the implementation4, an occasion on which the UE activates the first BWP is as follows:The SR associated with the first logical channel is triggered and notcanceled, and the SR-prohibit timer does not run. Because the UE cansend the SR associated with the first logical channel only when “the SRassociated with the first logical channel is triggered and not canceled,and the SR-prohibit timer does not run”, the UE activates the first BWPonly when the condition is met, to avoid a situation in which the firstBWP is activated excessively early, but the SR associated with the firstlogical channel cannot be sent on the first BWP, thereby reducing powerconsumption of the UE, and avoiding a network transmission resourcewaste.

It should be noted that, when there is no conflict, a plurality ofoptional implementations of the implementation 3 or the implementation 4may be combined. For example, when the SR associated with the firstlogical channel is triggered and not canceled, and the SR-prohibit timerdoes not run, the UE activates the first BWP, and starts the SR-prohibittimer after transmitting, on the first BWP, the SR associated with thefirst logical channel. Then, the UE deactivates the first BWP, andreturns to the second BWP on which the UE previously works. If the SRassociated with the first logical channel is triggered and not canceledwhen the SR-prohibit timer stops running, the UE re-activates the firstBWP, and after transmitting, on the first BWP, the SR associated withthe first logical channel, starts the SR-prohibit timer and returns tothe second BWP. In the foregoing manner, the SR can be transmitted in atimely manner, a network transmission resource can be effectively used,and power consumption of the UE can be reduced.

Optionally, in this embodiment of the present disclosure, the SRassociated with the first logical channel includes:

an SR triggered by a regular buffer status report BSR triggered becausenew data reaches the first logical channel; and/or

an SR triggered by a regular BSR triggered because a BSR retransmissiontimer expires, where the first logical channel is a logical channel witha highest priority in all current second logical channels of theterminal device, and the second logical channels are logical channelshaving available transmission data or logical channels having availabletransmission data and belonging to one logical channel group; and/or

a BSR triggered because a BSR retransmission timer expires, where thefirst logical channel is a logical channel that is in all current secondlogical channels of the terminal device and of which a value of eitherof the following two parameters in an associated transmission parameterset is smallest. The parameters include:

a parameter 1: a time length of uplink resource transmission; and

a parameter 2: a length of a time interval between control signaling forscheduling an uplink resource and the scheduled uplink resource.

The second logical channels are logical channels having availabletransmission data or logical channels having available transmission dataand belonging to one logical channel group.

Parameters in the transmission parameter set may include but are notlimited to at least one of the following items: a subcarrier spacing, acyclic prefix length, a time length of uplink resource transmission, alength of a time interval between control signaling for scheduling anuplink resource and the scheduled uplink resource transmission, and aserving cell of a terminal device corresponding to an uplink resource.

Optionally, in this embodiment of the present disclosure, in the severalpossible implementations in which the UE sends an SR, when the UEdetermines whether the SR associated with the first logical channel canbe transmitted in a time unit, in addition to the following conditions:(1) there is a physical resource that can be used to transmit the SR inthe current time unit, and (2) the SR-prohibit timer does not run, thefollowing condition further needs to be met: (3) the current time unitis not a part of a measurement gap.

Optionally, in this embodiment of the present disclosure, the time unitmay be implemented in a plurality of manners. The following describesthe time unit in detail by using specific examples. Certainly, the timeunit in this embodiment may include but is not limited to the followingimplementations.

In a first implementation, the time unit is a default/predefined timelength. For example, the time length may be a time length that is of oneslot and that includes a symbol length corresponding to a referencesubcarrier spacing. For example, the reference subcarrier spacing may bea subcarrier spacing of 15 KHz.

In a second implementation, the time unit is a transmission time lengthcorresponding to an uplink resource received by the UE. Differentsubcarrier spacings may be used for different uplink resources.Therefore, corresponding symbol lengths may be different. In addition,different uplink resources may occupy different quantities of symbols.Therefore, the UE receives uplink resources with different transmissionlengths.

In a third implementation, the time unit is a transmission time lengthcorresponding to downlink control signaling for scheduling an uplinkresource of the UE. Different subcarrier spacings may be used fordifferent downlink control signaling. Therefore, corresponding symbollengths may be different. In addition, different downlink controlsignaling may occupy different quantities of symbols duringtransmission. Therefore, the UE receives downlink control signaling withdifferent transmission lengths.

In a fourth implementation, the time unit is a default/predefined timelength including a symbol length corresponding to a subcarrier spacingin a transmission parameter set that can be used by or that is mapped tothe first logical channel. For example, the time unit may be a timelength that is of one slot and that includes the symbol lengthcorresponding to the subcarrier spacing.

In a fifth implementation, the time unit is a time length determinedbased on a symbol length corresponding to a subcarrier spacing in atransmission parameter set that can be used by or that is mapped to thefirst logical channel, and a default quantity of symbols occupied bydata transmission on the logical channel.

In a sixth implementation, the time unit is a symbol lengthcorresponding to a subcarrier spacing in a transmission parameter thatcan be used by or that is mapped to the first logical channel.

In a seventh implementation, the time unit is a default/predefined timelength including a symbol length corresponding to a subcarrier spacingthat is used by a physical resource for transmitting an SR and that isconfigured in an SR configuration mapped to/associated with the firstlogical channel.

In an eighth implementation, the time unit is a time length determinedbased on a symbol length corresponding to a subcarrier spacing that isused by a physical resource for transmitting an SR and that isconfigured in an SR configuration mapped to/associated with the firstlogical channel, and a quantity of occupied symbols.

In a ninth implementation, the time unit is a symbol lengthcorresponding to a subcarrier spacing that is used by a physicalresource for transmitting an SR and that is configured in an SRconfiguration mapped to/associated with the first logical channel.
